Find the factors and get the ones common to both of them

45=3 times 3 times 5
81=3 times 3 times 3 times 3
so the factors common to both are 3 times 3 which is 9

24 divide by blank plus 5 multipled by 3 plus 2 equals 20

Answer:

Step-by-step explanation:

The answer would be 8 because the question would be

24 ÷ x + 5 × 3 + 2=20 right?

The first thing you would want to do is multiply the 5 and the 3 because of PEMDAS which should give you 24 ÷ x + 15 + 2 = 20.

15 plus 2 is 17 and then you would subtract 17 from 20 which would give you 3. So you know know that 24÷x has to be 3 and 24÷3 is 8 so x=8.

Hope this helped!

50× 3/8 how to reduce answer to lowest te

hoa [83]

The lowest term is $\frac{75}{4}$ .

Solution:

Given expression is $50\times\frac{3}{8}$

<u>To reduce this term to the lowest term:</u>

$$50\times\frac{3}{8}=\frac{50}{1}\times\frac{3}{8}$

Multiply the numerator and denominator.

$$50\times\frac{3}{8}=\frac{150}{8}$

Now, divide the numerator and denominator by the greatest common factor.

Here 150 and 8 both have common factor 2.

So, divide numerator and denominator by 2.

$$=\frac{150\div2}{8\div2}$

$$=\frac{75}{4}$

$$50\times\frac{3}{8}=\frac{75}{4}$

Hence the lowest term is $\frac{75}{4}$ .
